The FPSO contract is the project’s largest, comprising engineering, procurement, construction, installation, commissioning and testing of the facility.
Dorado is an integrated oil and gas project which is planned to be developed in two phases. The initial development involves the production of oil and condensate through a well head platform (WHP) and FPSO. Gas will be reinjected in the initial phase to enhance oil and condensate recovery, followed by a planned future phase of gas production to backfill Santos’ domestic gas infrastructure in WA.
Dorado is a very low CO2 reservoir with approximately 1.5% CO2 and reinjection of gas in the initial phase, making it one of the lowest emission intensity oil projects in the region.
In June, the project entered the FEED phase, which involves numerous work-fronts including the award of contracts for the FPSO and WHP. The FPSO contract will commence with full definition engineering by Altera to confirm the technical requirements for the FPSO and associated disconnectable mooring system.
Santos CEO, Kevin Gallagher, said: “This contract is an important milestone for the project and Altera brings extensive FPSO design and operations expertise to the development.
“The FPSO design will provide for the integrated development of both the liquids and the gas resource and retains sufficient flexibility to support future nearby exploration success. A contract for the design, supply and installation of the WHP will be awarded soon.”
President, Altera Infrastructure Production, Chris Brett, said: “We thank Santos for putting their confidence in Altera and are eager to apply our over 30 years of FPSO competence and experience during FEED to deliver an FPSO design that meets the needs of the Dorado development while also bringing forward the latest emission reducing solutions in line with our vision to lead the industry to a sustainable future.”
Santos has an 80% interest in the Dorado project and is operator. The remaining interest is held by Carnarvon Petroleum.
